If you dont find anyone I can hook you up with some people that live in idaho and fish it or one of the rivers near by.
When are you going ? What kind of salmon are you targeting(silvers or kings)that will make a difference into what bait and technique works best.
For summer run:
There are 3 basic ways to fish for them a fly rod using a red or yellow maribou streamer
or casting and spinning rods using red cranks(I dont know if this would work for waters that far inland)
then there are the egg roa(sp) techniques which work all year long.
If you dont have a salmon /steelhead rig. I have one here that I would consider letting you borrow if and only if you returned it. I built it for fishing salmon egg roa's.
